Just pick the Xeon or the i7!
I have done the same mistake 7 years ago, dual core e7400 vs quad Q9650. Opted for the cheaper e7400 but you will always be thinking about that better cpu and finally you will switch it for the better ones and you end up spending the same or more money.
It is funny IŽam still trading from a 775 platform with a xeon x3360 and 4gb ram, and my cpu mark score is 5300, higher then the i3. I have looked for a new system but hesitate because I never had a system like this, it is rock stable.
I personally wouldnŽt want to miss the additional monitor outputs of the IGP and go with an E3-1225 v3 (no hyperthreading but as far as i know has better to be switched off for ninja anyways) or E3-1245 v3 with an Asrock Fatal1ty or Gigabyte G1.Sniper Z87 (both Qualcomm Atheros Killer E2201 network contoller for low latency with UDP and good sound onboard) or ASRock Z87 Extreme4 (Intel network controller, good sound)
Btw., the X99 chipsets (Haswell-e and DDR4 support) are rumored to come in june.
I found this info on utilizing the integrated graphics with a separate graphics card at the same time to drive four monitors. My initial build will only use 4 monitors, so I may start this way, which means the Xeon would have to go to a xxx5, or just go i series.
Haswell CPUs support up to 3 monitors simultanously with mainboards like i posted above.
You are free to add as many graphic cards as your board supports PCIe wise.
I just recently understood that you can use both. I had previously thought that adding a graphics card would disable the IGP ( told by local Tiger Direct, which is only partially true ), so I had been looking at the 3 displays supported as being useless since I wanted a minimum of 4.
But, now that I have looked nearly at every graphics card I can find, and considering my current needs + future wishlist, taking advantage of IGP seems like a better value. I will most likely never go back to being a gamer, and this build is as a dedicated trade box anyway. And, I have seen as many as 7 displays off a single laptop USB 3.0, and I already own one USB to DVI/HDMI converter that is driving the 3rd monitor on my current computer, so I may not even need a graphics card right now.
I did see that by going to a 1225/1245 that there is a significant drop in cpu mark compared to the 1230v3.
Today my study is on RAM, giving the processor issue a rest. I have put a lot of time into this, mostly because I have a lot of time. This new build had better purr!
The more I learn, the more I think 4 monitors may be the most I will ever use. If I were to upgrade, I may just go to larger displays with higher resolution. For example, four 42" displays could hold a lot of charts, and just yesterday I saw some marked down to $299 (refurbished) here locally. I was tempted to buy one, sell my three smaller monitors, and use just two displays for trading.
I did find a graphics card that supports 4 monitors for $95.
That is why I am spending so much time figuring out what I want. I could just buy the best of everything, make it a $1500 box and call it a day. But what keeps reigning me back in is the fact that my current trade computer has a cpu mark of around 400. And I have no complaints. So I build parts lists on PCPartPicker, then delete them and start over, thinking through various options, what will I use and what will I never use. Just going from a cpumark of 400 to 4000 would be huge (which I could do for 1/3 the cost of the 17 4770), am I really missing anything by not having a 9000+ score? Those types of thoughts.
Once it is built, as long as it works I will not question it. My guess is I can be a step or three behind the latest and greatest and be completely satisfied, for my use.
And, I am also upgrading my wife's computer, adding wireless HDMI transmitters to our laptops (for non-work things), bought a huge battery backup to run my entire setup (2 computers, modem, 4 screens, cellphone charger, speakers) for 16 minutes, etc. so some of what I save in the computer build I am seeing as going towards the other upgrades. A whole-house-trading-full-time upgrade, of which only part is the new box.
That TV probably has a max resolution of 1920x1080p. Whereas you can get 2560x1600 resolution on a 27" or 30" monitor. In other words, things will be huge, ugly, grainy, blocky, etc.
